While our eyes is on the fourth industrial revolution, we want to be part of the energy revolution and help to reduce the CO2 footprint in every single workplace. we move towards greener workplace by a software solution on energy optimization of dynamic mechanical systems (DMS). Our target industry for now is ventilation systems so called as HVAC for office building. The product is a software solution that monitors and optimizes energy consumption of HVACs. But why HVACs? Ventilations are installed in almost all office and industrial buildings. Only in Denmark, 12 M m2 of area is dedicated to offices and buildings. This corresponds to a huge energy consumption by HVACs (about 40% of total electrical energy consumption of a building and funny enough buildings are responsible for almost half of energy consumption of Denmark in a year). Despite of HVACs simplicity from system point of view, they are very complicated and confusing for the HVAC owners. The energy consumption and waste energy is not clear. Therefore, energy optimization becomes a long shot. 4i4’s product is solving these issues and brings values for the HVAC owners by peace of mind and valuable insight on how to optimize the energy and save on CO2 emission.
